# ConsumerIrManager

`public final class ConsumerIrManager`
`extends Object` ``

java.lang.Object
↳ | android.hardware.ConsumerIrManager

Class that operates consumer infrared on the device.
Requires the `PackageManager#FEATURE_CONSUMER_IR` feature which can be detected using `PackageManager.hasSystemFeature(String)`.

## Summary

### Nested classes
`class` | `ConsumerIrManager.CarrierFrequencyRange` Represents a range of carrier frequencies (inclusive) on which the infrared transmitter can transmit

### Public methods
`CarrierFrequencyRange[]` | `getCarrierFrequencies()` Query the infrared transmitter's supported carrier frequencies
`boolean` | `hasIrEmitter()` Check whether the device has an infrared emitter.
`void` | `transmit(int carrierFrequency, int[] pattern)` Transmit an infrared pattern This method is synchronous; when it returns the pattern has been transmitted.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Public methods

### getCarrierFrequencies

    public CarrierFrequencyRange[] getCarrierFrequencies ()

Query the infrared transmitter's supported carrier frequencies

Returns
`CarrierFrequencyRange[]` | an array of `ConsumerIrManager.CarrierFrequencyRange` objects representing the ranges that the transmitter can support, or null if there was an error communicating with the Consumer IR Service.

### hasIrEmitter

    public boolean hasIrEmitter ()

Check whether the device has an infrared emitter.

Returns
`boolean` | true if the device has an infrared emitter, else false.

### transmit

    public void transmit (int carrierFrequency,
                    int[] pattern)

Transmit an infrared pattern

This method is synchronous; when it returns the pattern has been transmitted. Only patterns shorter than 2 seconds will be transmitted.

Parameters
`carrierFrequency` | `int`: The IR carrier frequency in Hertz.
`pattern` | `int`: The alternating on/off pattern in microseconds to transmit.
